Shutdown crashed linux computer gently with REISUB

Debian doesn’t crash much but sometimes I manage to make it happen.

In that case, if you hold down Alt and the PrintScreen/SysRq key (top right of keyboard) whilst slowly pressing in order R then E then I then S then U then B, the computer will restart. (Leave maybe a second between keys).

Magic!

You can find this on a few places with more background info, for example here
